Multi-type air conditioner including a plurality of compressors, a
plurality of temperature sensors mounted in the plurality of compressors
for sensing temperatures in the compressors respectively, and an
equalizing pipe in communication with the plurality of compressors, for
uniform distribution of oil among the plurality of compressors according
to the temperatures sensed at the plurality of temperature sensors
respectively, thereby distributing oil among the compressors uniformly at
an exact time point at which the oil is distributed among the compressors
non-uniformly, not only to permit improvement of the performance of the
compressors, but also to permit improvement performance of the air
conditioner having the compressors.
